Answer this question truthfully
### Question: Who is at highest risk for Osteosarcoma ?
### Response: Age and height: Data suggest that the risk of osteosarcoma is highest during the teenage "growth spurt." Children with osteosarcoma are usually tall for their age. Radiation to bones: People who were treated with radiation for another cancer have a higher risk of later developing post-radiation (after radiation) osteosarcoma. Certain bone diseases: Some bone diseases such as Paget disease of bone and multiple hereditary osteochondromas may be risk factors of osteosarcoma. Inherited cancer syndromes: Syndromes such as Li-Fraumeni syndrome and retinoblastoma may increase the risk of developing osteosarcoma.
